  • Apparatus and method for detecting downlink transmit diversity at a mobile device
    Patent number: 7324617
    Abstract: A mobile device detects downlink transmit diversity. Slot and frame timing knowledge and a downlink scrambling code are applied to pilot and synch channels of the signal. An algorithm suited for the diversity case and an algorithm suited for the non-diversity case are utilized. The output of the diversity algorithm is compared to the output of the non-diversity algorithm. The output yielding the highest energy determines whether downlink transmit diversity is applied. The detection algorithms used in both the diversity and non-diversity cases use phasors to indicate the phase difference between two channels. This phase difference is the basis for determining diversity usage.
